WebApplications of these fluorescent and chromophoric analogs of N -ethylmaleimide (NEM) strongly overlap those of iodoacetamides, although maleimides apparently do not react with methionine, histidine or tyrosine. Reaction of maleimides with amines usually requires a higher pH than reaction of maleimides with thiols. WebAzo group. The part of an azo colorant molecule which produces colour, the chromophore group, is a double bonded azo linkage. The chromophoric group of azo colorants alters colour of a substrate, either by selective absorption or by scattering of visible light, i.e. light with wavelengths of approximately 400-750 nm.
